多吡唑烷配体与(CH_3CN)_2Mo(Cl)(CO)_3(GeCl_3)取代反应的研究

Studies on the Substitution Reactions of (CH_3CN)_2Mo(Cl)(CO)_3(GeCl_3) with Poly(pyrazol 1 yl)alkanes

通过多吡唑烷配体与（ＣＨ３ＣＮ）２Ｍｏ（Ｃｌ）（ＣＯ）３（ＧｅＣｌ３）中乙腈配体的取代反应， 合成了含多吡唑烷配体的Ｍｏ＿ Ｇｅ双核金属化合物． 多吡唑烷配体环上３，５ 位取代基的立体位阻以及４ 位取代基的电子效应均影响其配位能力． 通过元素分析、１Ｈ ＮＭＲ、ＩＲ和ＭＳ谱表征了所有新化合物的分子结构．

Mo_Ge bimetallic complexes containing poly(pyrazol 1 yl)alkanes have been synthesized by means of the replacement of CH 3CN ligand in (CH 3CN) 2Mo(Cl)(CO) 3·(GeCl 3) by poly(pyrazol 1 yl)alkanes. Due to the weaker donating ability, the replacement of bis(3,5 dimethyl 4 halopyrazol 1 yl)methane with (CH 3CN) 2Mo(Cl)(CO) 3(GeCl 3) requires heating to start the reaction. All new compounds were characterized by 1H NMR, IR, mass spectra and elemental analyses.
